STEAM STEERING MECHANISNI.

SPECIFICATION forming part of Letters Patent No. 300,180, dated June 10, 1884..

Application filed November 14l 1883. (Model.)

''o all whom, it may concern: Be it known that we, WILLIAM C. WILLIAM- son, a citizen of the United States, and HAL- VOR O. FLADVAD, of the Kingdom of Sweden, both residents of the city of Philadelphia, in

the county of Philadelphia and State of Ienn- Sylvania, have invented a new and useful Improvement in Steam Steering Mechanism, of which the following is a specification. io Our invention relates to starting, stopping,

and reversing the engine of a steam steeringmachine by means of spiral, curved, screw, or inclined shifting faces or ends, which lit together, andv operate by opening, closing, or reversing the engine-valve, whereby the ships rudder is consequently moved or held stationary.

On reference to the accompanying drawings, Figure l is a longitudinal vertical section of ism. Figs. 2 and 3 are views of the faces or ends by which the working of the valve is accomplished. Fig. et is a perspective view of the complete machine. Fig. 5 is a detached view of the shifting faces and accompanying parts.

Similar letters refer to similar parts in .the several views.

A is the housing of the drum-section of the machine, which in this instance is located in the pilot-house, though it may be otherwise suitably placed.

B is a hollow shaft, having a hand-wheel, C, fixed to it, and a screw-thread, a, Iformed 3 5 on itsterior, for engaging'with a stop-nut,

D, which moves in a guide, b, to prevent it 'l from turning, and thus retain its right-line motion.- A collar, E, of the hollow shaft B engages with the end c of a lever, F, centered at d. Through the medium of a rod, G, the other end, e, of the lever connects with the reverse link or other mechanism, which controls the motion and direction of the engine. H is the shaft of the supplemqgthhald-wheel I and the drum J, which are keyed t`o it. It is journaled at A A, and while revolving with the wheel and drum it turns freely and independently within the hollow shaft B, which it carries. Spiral, curved,screw, or inclined faces 5o f h are formed on the ends of the hollow shaft B. Like faces, g fi, are made on the adjacent the hand-wheels, drum, and shifting mechanfaces of the collars or hubs K L, which, being fixed to the shaft H, 'turn simultaneously with it. They are made to fit exactly, and have the same pitch vor` inclination.4

Vhen the hollow shaft B is turned in the direction of the arrow j by the wheel C, its curved end 71. advancingly presses against the` spiral face of the collar L, andthe end f and the face g give way to the pressure of the camfaces h i and permit the hollow shaft B to slide along the shaft H inthe direction of the arrow 7c. The lever F, partaking of the motion of the hollow shaft, is turned on its center d, and through the connecting-rod G the 65.

reversing-link M, Fig. 4, is operated for opening the steam-valve and starting the engine N. The power exerted by the engine is transmitted by the wrapping connection O from the wheel P to the hand steering-wheel I, and the 7C drum J ,which works the tiller chains or ropes Q for directing the rudder. The hand-wheel I, drum J, and hubs or collars K L, being fixed to and moving with the shaft H, have a simultaneous movement. Therefore, when the 7 5i hand-wheel I is turned by the rope O, the collar K turns with it, and while its spiral face g presses in a forward direction against the spiral end f of the hollow shaft B the spiral end h and the face i of the collar L give way in turning to the pressure and allow the hollow shaft to slide along the shaft H in the direction of the arrow Z. During this reverse sliding of the shaft B it is held from turning by the person at the wheel C. The lever F, partaking of the sliding motion, operates the link M by the rod G and gradually closes the valve, by which the engine is stopped and the rudder held in the required position.

It is evident that the spiral faces or ends operate the valve which controls the admission of steam to the engine. When they are moved by the wheel C, the valve is opened for running the engineover or under, according to the direction given to the wheel in turning. When they are operated' by the auxiliary wheel I, they serve to close the valve, shut off the steam, and stop the engine when the rudder has reached the desired inclination. Should the engine break down or become interrupted in any manner, the auxiliary wheel I can be used for steering -by hand by throwing off the rope O and disconnecting the link M. The rotation ol' the wheel C either way is limited by the travel of the nut D in the guide b, the length of which is determined by the degree of vibration ot' the rudder. Vvfhen the offsets of the spiral faces g f, Figs. 2 and 3, contact, the valve is wide open and the engine is running over or under.

We do not confine ourselves to the precise details of construction as illustrated and described, but reserve to ourselves the right to change the same in any manner that experience or necessity may suggest.

Ve claim as our invention- 1. In a steam steering-machine, sleeves having spiral, curved, screw, or inclined end faces moved by the steering-wheel and connections, and appliances for controlling the motion of the steering-engine and governing the rudder, substantially for the purpose set forth.

2.' In asteain steering-machine, sleeves having spiral, curved, screw, or inclined end i'aces and connected with the engine, and appliances connected with the engine for controlling the action of the same and governing the rudder, substantially for the purpose set forth.

3. The combination, in a steam steeringmachine, of a hand-wheel provided with cam- -faces adapted to contact, as described, with collars having cam-faces and operated by the 30 tiller-druin, and connections for starting, stopping, and reversing the engine, substantially as set forth.

4. In a steam steering-machine, the combination of a hollow shaft, B, having spiral, curved, screw, or inclined ends,with a drumshaft, H, having like ends or collars, for starting, stopping, or reversing the engine.

5. In a steam steering-machine, the combination of a hollow shaft, B, having spiral, curved, screw, or inclined ends, a drum-shaft, H, having ends or collars, collar E, link F, and rod G, for starting, stopping, or reversing the driving-engine.

6. In a steam steering-machine, the combination of a hollow shaft having spiral, curved, screw, or inclined ends, a drinn-shaft, H,'hav ingV like ends or collars, a hand-wheel, I, drum Q, link F, and rod G, for starting, stopping, or reversing the driving-engine.
